Intake Manifold Gasket?
Hi, I have a 77 f150 with the 351m engine. I noticed that there is fluid pooling up on top of the block right behind the intake manifold. Right around the oil pressure sensor.
Anyway I got under there and collected some of the fluid expecting it to smell of fuel, but it has no smell at all. Could this be a coolant leak caused by a bad intake manifold gasket? I assume that there are coolant passages in the intake manifold on these engines. Ive also been trying to fix (what I thought was an exhaust leak) for a long time now and am wondering if the noise im hearing is due to that intake not sealing.
Thanks in advance for all the help.

Yep. I bet thats exactly what it is. The truck doesnt even have that seal anymore. And it has been raining a lot lately. Thanks for the info!
